Answer:
the answer is 78 degrees
Step-by-step explanation:
a acute angle is less than 90
bearing in mind that parallel lines have the same exact slope, then any parallel line to the one above will have the same slope as that one.

The length of the ramp is 61 feet.
<h3>What is the length of the ramp?</h3>
In order to determine the length of the ramp, Pythagoras theorem would be used.
The Pythagoras theorem: a² + b² = c²
where a = length
b = base
c = hypotenuse
√11² + 60²
√121 + 3600
√3721
= 61 feet
